I have a fox trot Mike ranch rifle. It's like a mini 14 and an ar 15 made a baby. Uses standard ar15 mags , it's a bufferless ar15 upper on a specialized lower. California compliant featureless uses your legally acquired standard capacity magazines. Chambered in 300 blackout , 13.9" barrel with a pin and weld strike compensator , a 0-6 LPVO , magpul stock with two different cheek risers and magpul folding bi pod. Shoots great small groups at 100 yards. 800$ obo
